Perimeter of triangles is 6x + 12, 18x + 12, 12x - 9 and 14x - 4.

What is perimeter of a triangle?

The perimeter of any two-dimensional figure is defined as the distance around the figure. Therefore, perimeter of a triangle is sum of three sides of a triangle.

According to the given question:

Perimeter of given triangles is

1) Sum of all sides of triangle 1

= (x + 6) + (3x + 2) + (2x + 4)

= 6x + 12

2) Sum of all sides of triangle 2

= (6x + 4) + (7x + 1) + (5x + 7)

= 18x + 12

3) Sum of all sides of triangle 3

= (4x - 3) + (3x) + (5x - 6)

= 12x - 9

4) Sum of all sides of triangle 4

= (6x - 8) + (3x + 7) + (5x - 3)

= 14x - 4

Answer:

Step-by-step explanation:

a) x = 1.786 & -1.120

Explanation:

Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.

The derivative of this equation $x^3 =x^2-6x[/t[tex] is [tex]3x^2+2x-6$ .

Solving the equation $3x^2+2x-6=0$ using the quadratic formula we get 1.786 & -1.120

b) x = -3, x=0 and x=2

Explanation:

The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2

Does changing the position of the vertex affect the volume if the height remains the same? Why or why not? (Hint: Think of the c

steposvetlana [31]

Answer:

<h2>It doesn't change the volume.</h2>

Step-by-step explanation:

If we change the position of the vertex of a cone, it won't change its volume, because we're not changing its height.

When we change the position of the vertex of the cone, we are moving it to left or right, which would give a slant cone. However, its dimensions are the same. The important fact here is that the dimensions of the cone don't change, that's why it would give the same volume.

Find the domain of each function. (Enter your answers using interval notation.)(a) f(x)=8/(1+e^x) .(b) f(x)=5/(1−e^x)

Alexus [3.1K]

Answer:

domain is (-∞,∞)

(-∞,0) U(0,∞)

Step-by-step explanation:

$f(x)=\frac{1}{1+e^x}$

The domain is the set of x values for which the function is defined

In f(x) there is no restriction for x. the function is defined for all x values

so domain is (-∞,∞)

$f(x)=\frac{5}{1-e^x}$

The domain is the set of x values for which the function is defined

when x=0, e^0=1 that makes the denominator 0

Denominator 0 is undefined. So x cannot be 0

domain is (-∞,0) U(0,∞)
